Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574594, here are decompositions:

31 + 31574563 = 31574594
97 + 31574497 = 31574594
127 + 31574467 = 31574594
151 + 31574443 = 31574594
157 + 31574437 = 31574594
421 + 31574173 = 31574594
463 + 31574131 = 31574594
487 + 31574107 = 31574594

Showing the first eight; more decompositions exist.
